Tubular capacitors needed for HO-10/SB-610

I was sent the following eMail from Jim, WB2FCN regarding my request for
"electroylic" capacitors for the HV of the HO-10/SB-610 monitor scope...upon
receiving this I went back to the manuals...and Jim is correct!  Electrolytics
are used in the low voltage (600V/280V/265V not the -1430V) and So now I need
to look for just some non-electrolytic caps.....thanks Jim for setting me
straight & forcing me to re-read the parts list correctly.  Perhaps Mouser or
others have some.  73, Larry KC8JX

Hi Larry, those caps aren't electrolytics, the are tubular wax or "other", I
across some .15uF at 1500 vdc and put them in my SB-610. The job of the caps is
for the voltage tripler the transformer puts out like 300-400 volts and that is
multiplied up to get the high volts for the crt. Unlike the HO-10 which has a
1V2 rectifier and hv winding, those guys are the filter for the rectifier
output across 220K resistor, not much filtering but the crt doesn't need it.

I'm sure this has been asked many times....but, I would like a source to buy
several electrolytics for my HO-10's and SB-610 monitor scope.  I'm looking
for the .1ufd @1200V and .15ufd @1600V.  Any leads would be deeply appreciated.

Thanks in advance............73, Larry KC8JX

May your days be full of sunshine and good thoughts fill your head.
